Hi,
I have a entity named Learnitem having a blob field inside:
@Entity
@Table(name = "learnitem")
public class Learnitem implements Serializable {
...
private Byte[] learnitemDocument;
@Basic(fetch = FetchType.LAZY)
@Column(name = "LEARNITEM_DOCUMENT")
@Lob(fetch = FetchType.LAZY, type = LobType.BLOB)
public Byte[] getLearnitemDocument() {
return this.learnitemDocument;
}
public void setLearnitemDocument(Byte[] learnitemDocument) {
this.learnitemDocument = learnitemDocument;
}
...If I try to read the content of that field I got :
11:59:54,137 INFO [SerializableType] could not read column value from result set: LEARNITEM3_21_0_
11:59:54,137 INFO [DefaultLoadEventListener] Error performing load command
org.hibernate.type.SerializationException: could not deserialize
at org.hibernate.util.SerializationHelper.deserialize(SerializationHelper.java:211)

at org.hibernate.type.SerializableType.fromBytes(SerializableType.java:78)
at org.hibernate.type.SerializableType.get(SerializableType.java:39)
...
Any ideea why ?
If the binary content in the DB is null the system reads the LearnItem without problems.
Any workaround ?
Note: I'm using jboss 403 and 403SP1, MySQL 5.0 and mysql-connector-java-3.0.15-ga-bin.jar
Thanx in advance.
